#Upgrade and migration

Preparation

Backup your data

Shaarli stores all user data under the data directory:

• data/config.php - main configuration file
• data/datastore.php - bookmarked links
• data/ipbans.php - banned IP addresses

See Shaarli configuration for more information about Shaarli resources.

It is recommended to backup this repository before starting updating/upgrading Shaarli:

• users with SSH access: copy or archive the directory to a temporary location
• users with FTP access: download a local copy of your Shaarli installation using your favourite client

Migrating data from a previous installation

As all user data is kept under data, this is the only directory you need to worry about when migrating to a new installation, which corresponds to the following steps:

• backup the data directory
• install or update Shaarli:
  • fresh installation - see Download and installation
  • update - see the following sections
• check or restore the data directory

Upgrading from release archives

All tagged revisions can be downloaded as tarballs or ZIP archives from the releases page.

We recommend using the releases from the stable branch, which are available as:

• gzipped tarball - https://github.com/shaarli/Shaarli/archive/stable.tar.gz
• ZIP archive - https://github.com/shaarli/Shaarli/archive/stable.zip

Once downloaded, extract the archive locally and update your remote installation (e.g. via FTP) -be sure you keep the contents of the data directory!

After upgrading, access your fresh Shaarli installation from a web browser; the configuration will then be automatically updated, and new settings added to data/config.php (see Shaarli configuration for more details).

Upgrading with Git

Updating a community Shaarli

If you have installed Shaarli from the community Git repository, simply pull new changes from your local clone:

$ cd /path/to/shaarli
$ git pull

From github.com:shaarli/Shaarli
 * branch            master     -> FETCH_HEAD

Migrating and upgrading from Sebsauvage's repository

If you have installed Shaarli from Sebsauvage's original Git repository, you can use Git remotes to update your working copy.

The following guide assumes that:

• you have a basic knowledge of Git branching and remote repositories
• the default remote is named origin and points to Sebsauvage's repository
• the current branch is master
  • if you have personal branches containing customizations, you will need to rebase them after the upgrade; beware though, a lot of changes have been made since the community fork has been created, so things are very likely to break
• the working copy is clean:
  • no versioned file has been locally modified
  • no untracked files are present

Step 0: show repository information

$ cd /path/to/shaarli

$ git remote -v
origin	https://github.com/sebsauvage/Shaarli (fetch)
origin	https://github.com/sebsauvage/Shaarli (push)

$ git branch -vv
* master 029f75f [origin/master] Update README.md[](.html)

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

Step 1: update Git remotes

$ git remote rename origin sebsauvage
$ git remote -v
sebsauvage	https://github.com/sebsauvage/Shaarli (fetch)
sebsauvage	https://github.com/sebsauvage/Shaarli (push)

$ git remote add origin https://github.com/shaarli/Shaarli
$ git fetch origin

 * [new branch]      master     -> origin/master[](.html)
 * [new branch]      stable     -> origin/stable[](.html)

 * [new tag]         v0.7.0     -> v0.7.0[](.html)

Step 2: use the stable community branch

$ git checkout origin/stable -b stable
Branch stable set up to track remote branch stable from origin.
Switched to a new branch 'stable'

$ git branch -vv
  master 029f75f [sebsauvage/master] Update README.md[](.html)
* stable 890afc3 [origin/stable] Merge pull request #509 from ArthurHoaro/v0.6.5[](.html)

Optionally, you can delete information related to the legacy version:

$ git branch -D master
Deleted branch master (was 029f75f).

$ git remote remove sebsauvage

$ git remote -v
origin	https://github.com/shaarli/Shaarli (fetch)
origin	https://github.com/shaarli/Shaarli (push)

$ git gc

Step 3: configuration

After migrating, access your fresh Shaarli installation from a web browser; the configuration will then be automatically updated, and new settings added to data/config.php (see Shaarli configuration for more details).
